MfS-* IMPROVEMENT IN EARTH-CLOSETS.

The Schedule referred to in these Letters Patent and making part 0f the Same.

We, JAMES A. DRAKE and WiLLIAM R. C. CLARK, of the city of New Orleans, State of Louisiana, have invented certain Improvements in Earth Closets, of which the following is a specification.

Nature and Object of the Invention.

Our invention consists of a mechanical arrangemeut for holding in reserve, in earth closets and commodes, dry earth or other deodorizing substance, and for precipitating the same in regulated and prescribed quantity upon each deposit of excrement before another is made, which is alike simple in its nature, and inexpensive in its construction, and evcient in its actual operation or practice, the object Description of the Accompanying Drawings. Figure 1 is a vertical section, the bisection being .from the front to the'rear of an earth closet, showing in part the hopper for containing the deodorizing substance, the sliding receptacle for precipitating the same upon the excrement, with the mechanical arrangement for operating the latter on one side of the closet, there being a duplicate on the other side which is not shown, and

Figure 2, a similark section through line a b of fig. 1, showing form of hopper, &c. n

Referring to the drawings, it will bc seen that just vbehind the seat of the closet I place a hopper, which is divided into three distinct compartments by the inclined partitions A A A" A".

This divisional arrangement is intended to preventthe packing and lateral pressure of the earth or other deodon'zing agent` by giving it several bearings, and lin this way, also, to reduce its columnar pressure ou the ksliding box B, which is sustained on aixed roller, B', and a movable shaft, B", resting on wheels c a.

The wheels of shaft B" are supported in rebates in the'fxed frames G C', as shown.

This shaft being firmly secured to the sliding box B moves with the' same, while the roller B' is supported in stationary journals D D', the former only being shown on the drawing.

The sliding box B is provided with a vibrating front end, having wings E at each of its ends, through which the pivot b, ou which it vibrates, passes, and is secured in the sides of the box B, which fit closely up against the sides of the hopper at their'npper edges, and thus make the bottom of said box the bottom of the same. l

Outside the box B supplemental sides F, extending to c, are placed, to serve as guides for the same-and to close the end E by the impingement of the corners c of the wings E against the ends c, as the box is carried back under the hopper.

This movement iseiected by means of a hinged lid, G, and two armsgor levers G G that are pivoted together and connected, the one to the boxby an articulating joint, and the other to said lid in a lixed or immovable manner, a little way behind it by an elbow section. v

These arms are shown in dotted lines at fig. 1, and they are so adjusted that when the lid G is shut .down on the seatof the closet or commode, they will throw the box forwardsufficiently to bring its front end precisely over the deposit of fecal matter.

In order, when this is done, that a precipitation of the absorbing'or deodorizing agent may take place upon the said matter, chains or cords H are each secured at one one of their ends to the vibrating end E, near its top, and at each of their other ends to the beam or part to which the lid is hinged.

The length of these `chains is so regulated that, when the hinged cover or lid Gr is turned down on the seat, they will draw back the upper part of the end E, and thus throw forward the lower part, as shown at iig. 1, and hence'cause thedeodorizing substance, which isl proximate to and banked up against said end, to fall out; and, inasmuch as the tilting of the said end is effected in a gradual or progres-y sive manner as the box slides forward, it necessarily follows that the precipitation of the, earth is done inthe same manner, and that it is hence spread out over the whole of the fecal matter, with nnvarying regularity.

The box is` thrown back through the agency of the arms G G" by simply raising up the lid, and, as it slides back, the Vibrating end 'E is closed, as we have before stated, by the impingement of the wings E' against the vertical ends ot' the guiding sides F.

The operation of our invention, it will be observed, is very simple, the raising and lowering of the hinged lid alone being necessary thereto.

Any proper receptacle for deposits may be placed under the seat in such manner that it may be removed at pleasure.
